BACKGROUND:Exor is Smithy's Giant Sword that crashed into Bowser's Keep, allowing the Smithy Gang to enter the Mushroom World and take over Bowser's Keep. Exor also destroyed the bridge so nobody could get to the Keep.
Exor seemed to have a hypnotic power over Bowser's Minions, and he is believed to have shattered the Star Road. He's probably the second-largest weapon in the Smithy Gang after the Blade.
